Firmware Update

This guide shows you how to update the firmware on your Open Mower.

Warning

Early versions of the xCore board have a bug in the bootloader which sometimes prevents the board from being detected by the openmower tool.

If you encounter Timeout errors during the firmware installation process, update the bootloader by running: openmower update-bootloader and try again.

To install the firmware to the xCore board, simply run: openmower update-firmware. The openmower tool will read your environment variables, download the appropriate firmware binary and upload it to the xCore board via Ethernet.

The expected output is shown below:

Example output for openmower update-firmware command.
